BENJAMIN D. EMANUEL, OF HAMILTON, OHIO, ASSIGNOR TO THE PIERCE SPEED CONTROLLER COMPANY, OF ANDERSON, INDIANA, A CGRPORATIGN.

COMBINED SPEEDOMETEB AND SPEED-CONTRQLLER.

Application filed January 24. 1913,

To all w-lmm it may concern Be it known that i, BENJAMIN D. EMAN- UEL a citizen of the United States. and a resident-of Hamilton county of Butler, and

State of Ohio. ha e invented a certain new and met l Combined Speedometer and eters mid speed eontmllers'for and in con-"- ncction with automobiles or other cars or vehicles By speedometer is meant here in any device for indicating either the speed or the mileage, or both, and the invention is not limited to any particular type or construction of speedometer 0r odometer or speed controller. By speed controlle is meant, as used herein, any automatic means arranged to limit the speed "tirhlllCl! an nu tomobile or the like can be driven.

The chief feature of the invention consists in driving one of said parts the speedon'zeter and the speed controller.-frem the other and preferably in driving the speed controller from the speedometer. Thus, with this or rangement said two piirts or mechanisms are associated together mechanically so that the operation of one controls the operation of the other. As long as the speedometer on erntes, thespeed controller will likewise be in operation and one cannot stop the opera tion of one bf said pertswitlmut stopping the other. Therefore, the speed controller is desired often by the owner of an automobile to prevent an automobile from being driven by a chauffeur or any one else at too high sped. If the arrangement be such, however, that the chauffeur could readily disengage the speed controller or thespeednmeter then he col-dd be relieved from the limitation of the speed controller. Furthermore, the practical dev'ee herein shown has the advantage of the speed controller being driven directly by the speedometer, or the two driven by the some means so that thereis a fixed relation between the action of the speed controller and the operation of the speedometer.

The nature of the invention will be under- Specification of Lztters Patent.
